// Created a long, long time ago by Tanny O'Haley
// Update history.
// 24 Oct 2006 - Added to http://tanny.ica.com
// 14 Jul 2006 - Modified the way the iframe is added to the DOM. I no longer use 
//			innerHTML but use DOM methods.
// 15 Sep 2006 - Added a check to see if the target element onmouseout is contained
//			in the onmouseout element. If it is then I dont' remove the
//			sfhover class. I made use of the Microsoft proprietary
//			obj.contains() method.
//		 Added check to make sure that the sfhover class is not already in
//			the li element.
